This is Serious Mum (person)

A "band" from Melbourne, Australia that is well-known for their bizarre and twisted sense of humour. Who the members of TISM (as they are commonly known) are is not known; they all perform on stage wearing balaclavas; and they use stage names like: Ron Hitler-Barassi (Ron Barassi is one of the best known players of Australian Rules football), Humphrey B. Flaubert (Humphrey B. Bear is a famous children's show character), Eugene de la Hot Croix Bun, John St Peenis, Jock Cheese, and Tokin Blackman.
